Flow Ventilation® is possible because of the patented device called the Phasitron® by Percussionaire. The Phasitron® is a unique venturi that acts as a “clutch” mechanism to protect the lung from over pressure. By automatically adjusting to the resistance of the lung, the Phasitron® precisely and safely delivers the optimal volume and pressure of air required by the alveolar space.
Percussionaire Flow Ventilators
- All Percussionaire devices use the Phasitron® to safely and precisely provide lung expansion, secretion clearance, and oxygen in one convenient delivery system.
- The Phasitron® Flow Ventilator is an open circuit which accommodates any patient lung volume regardless of compliance.
- The Phasitron® Flow Ventilator works equally well for all patient populations from NICU & PICU to ICU and clinical and outpatient situations.
- Percussionaire Flow Ventilators are used around the world under all conditions.
The pulmonary flow created by the Phasitron® is known as Pulsatile Flow which bathes the alveoli in fresh oxygenated air while gently washing out CO2 and secretions.
Flow Ventilation® is a Pulsatile Flow that mobilizes and removes mucus and debris, while gently recruiting alveoli and restoring FRC. Unlike external percussion that may drive secretions deeper into the lung, the Pulsatile Flow continues to dislodge debris and secretions which are carried out by the exiting airflow.
Over time, the Pulsatile Flow gently persuades distal airways and collapsed alveoli to open which keeps lung supported and respiring while atelectasis, infection, inflammation, and injury can heal.
